Thank you, I like such settings and was impressed how well it works and how much fun it offers. It’s a great alternative for guys who don’t like the moving dildo of a fuck machine.

Slave and sub could test the new pump plug machine. While one plug is filled the other was deflated and vice versa. So it’s a more comfortable way to enjoy being fucked because there is no in and out move. Video follows.

I think I will never understand why my slave loves ball slapping so much. He asked for mehr —> more! so I increased speed #cbt

Ball slapping automation hasn’t worked as planned because motor was not fast enough but there is always a solution 😈 - good I had my tools with me 🤭

I wonder if they had fun with the vibrator? Slave in a chastity device, sub without but unable to reach the vibrator. 😈 #Bondage #chastity

A few day ago I took care of the balls of a very special guy 😉😄. For him it felt like he was on the verge of cumming for an eternity. The salvation was all the more intense.

Ein pneumatikzylinder, das genutzte Volumen muss zum Plug passen und vom Motor bewegt werden können.

Ist separat bestellt, heißt linear aktuator. Muss aber viel Schubkraft haben 5-7 kg bei 6-8 cm hub.

Da kann ich den Zylinder passender wählen und den Hub vom linear aktuator einfacher anpassen. Ich empfehle auch nicht den Motor der 700€ teuren tremblr dafür zu nutzen.

New setup for an automated pump plug - instead of using the tremblr I build a much cheaper machine to fill the pumpplug - so it’s like being fucked but not with in and out moving dildos. Enjoy - soon tests with my slave start. For questions ask me.

Ja das geht indem man den Hub der Maschine verändert. Mit meiner neu gebauten Maschine geht das aber einfacher.

My slave tried it once with the tremblr as motor for the plug and he said it’s better than the fuck machines. That was the reason I was thinking about a better solution. Will keep you updated how it was.

Thinking about combining a pulsating dildo with a fuck machine so in/out and diameter change 😅

Yes, always good to hydrate them, they always sweat so much wearing rubber 😈

I‘m so sorry to hear. Accidents can always happen no matter how careful you are, so please never do BC alone.
